{Official User Manual}

The official user manual should work fine already.  However, for beginner users, the following details would be helpful too.

 

{Get Your Network Ready}

The default IP of the miner is 192.168.1.254“. So you need to:

  1. Make sure the IP address of your router is “192.168.1.x“(the ‘x’ should be a number between 1~253). Or you need to change the IP address of your router to “192.168.1.x”
  2. Make sure there are no other devices which are occupying the default IP address of the miner(192.168.1.254). Otherwise, you maybe can’t login to the configuration page of the miner.

In Windows, please use the “ipconfig” command to find out your network details.

How to find out your network details:

  1. Press “Win Key + R“, then a “RUN” box will be shown.
  2. Type “cmd” in the text box and then hit the Enter key on your keyboard.
  3. A black box with a flashing cursor will open; this is the Command Prompt.
  4. Type “ipconfig” and then hit the Spacebar on your keyboard. Then type in the address you’d like to ping and then hit the Enter key on your keyboard. After a bit, you will get the network result. The “Default Gateway” in the result is the IP address of your router.

{Miner Connection}

  • Get your PSU ready. You need to prepare a PSU > 750w with 6pin x 9 for the miner. Check here for the Setting-up for PSU.
  • For the miner configuration, please connect the miner to the LAN port on the same router which your computer is also connected to. The miner is stand-alone, your computer is just needed for the miner configuration.
  • This is the Innosilicon A4+ you will receive. For obvious reasons, newly developed miners (by different manufacturers) all look similar which actually works more easily for users.

  • Please check if all the cables on the miner are inserted tightly.
  • There are NINE 6PIN ports on the miner(2 ports on each hashing boards, and another one on the controller). All the NINE 6PIN ports are needed.

  • The mining will automatically start after a few minutes. Navigate to the “Miner Status” page and keep refreshing the page until some data (Speed, miner account, pool etc.) is shown on the page (which means the machine has started mining. Generally, the miner needs about 3~7 minutes to start mining).

{Running More than One Miners}

If you are going to run more than one A4+ LTCMaster miners at the same time, you need to:

  • Connect and configure miners ONE BY ONE.
  • After configuring a miner, you need to CHANGE the default IP of that miner to a different one (DON’T keep the default IP 192.168.1.254). So you can configure another miner via the default IP “192.168.1.254”.

How to change the default IP address of the miner:

  • Click the “Network” tab on the configuration page.
